Im following this guide https://github.com/serkodev/rabbitmq-cluster-docker/blob/master/docker-compose.yml I have the first instance up and running but when I try to run the second instance it just hangs here

Starting RabbitMQ Server for host: railway

Waiting for pid file '/usr/var/lib/rabbitmq/mnesia/rabbit@railway.pid' to appear

Starting RabbitMQ Server for host: railway
